281079.（2025•铁一中学•高二上一月） After a long and busy day at school or work，all we want to do is return to a clean and comfortable home.Smart technology can turn any home into a nicer place to live.You can now turn your thermostat （恒温器） up，lock your doors and play your music with a simple voice command. In fact，smart homes have actually been around for some time.Scottish company Pico Electronics invented a communication protocol （协议） called X10 back in 1975.With radio waves，this protocol allowed users to communicate with various devices in their homes，such as lights and alarms，according to AVSystemsMag，a magazine dedicated to the AV and automation industry. Of course，4 G-and now 5 G-wireless technology makes smart homes much more sophisticated （复杂的） and powerful than X10 devices.Perhaps the most widespread smart home technology is the voice-activated assistant.Google Home and Amazon's Alexa allow users to interact with nearly any device in their homes simply by speaking a few words.This is especially convenient for children and people with physical disabilities，as they can accomplish tasks that would normally be too complicated or difficult，according to How To Geek magazine. Common household appliances can become "smart" as well.For example，a smart trash bin can monitor the things you've thrown away and place an online order for replacement items，while smart refrigerators can create dinner recipes based on the ingredients that were kept inside，according to How stuff works website.5 G-powered sensors and cameras can monitor almost every aspect of household life. The appeal of all of this convenience has paid off for realtors，who are seeing sales of smart homes skyrocket.You can ask Dave Garland，a realtor with Second Century Ventures. "There's a new narrative when it comes to what 'home' means，" he said in an NPR report. "It means a personalized environment where technology responds to your every need." But it's not just about convenience.Smart homes are also good for the environment.By monitoring your energy use and automatically turning off lights and other devices that you are not using，smart homes can lower how much electricity you use overall.Using less energy means that we use fewer resources such as coal and gas，which is ultimately good for the environment-and our wallets.Well，not everyone is excited about smart home. 32. Where is this passage most probably from？ A.A book report. B.A science magazine. C.A research paper. D.A guidebook. 33. What is Paragraph 3 mainly about？ A.Household devices designed for the disabled. B.All types of smart household appliances. C.Further development of smart home technology. D.Difference between X10 and 5 G network. 34. How does smart home technology influence our life？ A.Smart trash bins help us find cheap but nice things online. B.Smart fridges can create proper recipes and cook tasty food. C.Smart homes will help us save energy and reduce pollution. D.Smart homes make us stay at home instead of working out. 35. The author may introduce the of smart homes in the next paragraph. A.application B.development C.regulation D.drawback

Using AI，a group of researchers from Dalhousie University have begun the surprisingly complicated work of translating the language of chickens.This groundbreaking study about chicken vocalizations（发声） could have positive effects on chicken welfare. Chicken"speech" is actually a lot more complex than one might think-they squawk，cluck，and even purr.And the way they communicate with one another can be affected by their environment，age，and level of domestication（驯化）.In addition，according to The Debrief，chickens also communicate via visual cues such as body language and facial expressions. Luckily，the researchers were able to use new AI technologies to help interpret what chickens are saying.According to The Conversation，AI can process and analyze huge amounts of audio（音频的） data.It can recognize patterns and types of vocalizations.Using this information and an AI technique called Natural Language Processing，the researchers have begun to interpret the emotional states of chickens. In addition，the researchers also used data from video and thermal imaging（热成像），tracking the chickens' expressions and facial temperatures.This can be used to track how chickens respond to stressors. Neethirajan，an expert in stock farming（畜牧业），and the lead researcher of the study，told The Conversation that his team's interest in chicken communication is not just academic.The researchers hope that this could be a turning point in terms of stock farming. "Farmers can use this knowledge to create better living conditions，leading to healthier and happier chickens.This，in turn，can impact the quality of produce，animal health and overall farm efficiency，" he said.Additionally，he advocates for the use of this information to influence animal welfare policies.The more people understand animals，the more likely they are to care about their well-being.
28. The underlined word"welfare" is closest in meaning to . A.social security B.happiness C.communication D.domestication 29. What can we know about chicken"speech"？ A.It is easy to understand. B.B.It is similar to other animals'. C.It follows the same pattern. D.It is influenced by multiple factors. 30. What role does AI play in the research？ A.It deals with audio data.

In the American Journal of Physics，three high school students from Portugal，along with their teacher，have reported the results of their project.The students programmed an add-on （附加装置）board for the Raspberry Pi computer to map out Earth's magnetic field （磁场）. The European Space Agency teamed up with the U.K.'s Raspberry Pi Foundation to hold a competition for high school students.The competition，known as the Astro Pi Challenge，required the students to program a Raspberry Pi computer to be run aboard the International Space Station （ISS）. The students used the data （数据） from the space station to map out Earth's magnetic field and compared their results to data provided by the International Geomagnetic Reference Field （IGRF国际地磁参考场）. " "I saw the Astro Pi Challenge as a way to increase my knowledge and skill set，and it ended up introducing me to the exciting reality of the practical world，" Louren?o Faria，co-author and one of the students of the project，said. The IGRF data is updated （更新） every five years，so the students compared their results，taken in April 2021，with the latest IGRF data from 2020.They found their data differed from the IGRF results.This difference could be because of the magnetic field inside the space station. The students repeated their tests using another set of data from ISS and found a good improvement in results.The students thought it astonishing that the main features （特征） of Earth's magnetic field could be remeasured （再次测量） with only three hours' worth of computing from their low-cost add-on board in the space station. Although this project was carried out aboard the space station，it could easily be applied to ground-based measurements using apps for smartphones. "Taking measurements around the world and sharing data through the Internet or social media would make for an interesting science project that could connect students in different countries，" said Alex Mora，manager of Raspberry Pi Foundation.
（1）What did the three students do in the Astro Pi Challenge？ A．They made a new Raspberry Pi computer. B．They computed Earth's magnetic field. C．They developed new apps for ISS. D．They helped the IGRF collect data. （2）What did Faria say about the Astro Pi Challenge？ A．It should include more students from different countries. B．It made him realize the importance of knowledge. C．It was a great chance for self-improvement. D．It should get more international attention. （3）What does the underlined word" astonishing" in paragraph 6 mean？ A．Necessary. B．Impossible. C．Dangerous. D．Surprising. （4）What was Mora's attitude to the project？ A．Uncaring. B．Doubtful. C．Curious. D．Positive.

Hunger is a very real problem around the globe.This year，almost 7 million people have died of hunger already.Why do people still die of hunger when there's more than enough food in the world？ Well，considering that there are places in the world where basic needs like housing and clean，drinkable water are not met，then it doesn't come as a surprise that food is just not accessible to them.The food exists—it just doesn't get to where it needs to be. Nigerian farmer Samson Ogbole decided to go ahead and cultivate（培育） fruit and vegetables in a different way.Ogbole's farming process centres around two concepts：soilless farm-ing and aeroponics（气雾栽培）.To put it simply—he's growing food in the air. As Ogbole explained during a TED talk，aeroponics is the future of agriculture because it offers many benefits.For example，it is cheaper than traditional farming because there is no need to hire as many workers since everything is done with a"click".Also，this kind of farm-ing is more environmentally friendly since farmers don't use pesticides.At the same time，there are no space limitations—planting in the air means you can plant as many layers as you like.The sky is the limit literally! So，the young farmer has been practicing aeroponics for more than five years with impressive results.His work was recently praised on social media this summer when he was featured in a network post.In the post，Ogbole's farming method was mentioned，and Internet users had the chance to see pictures of the farmer's produce. Many viewers think southern Nigeria needs this method to grow crops.This will help in bringing down the price and avoiding future food blockades from the north.It seems that people are already realizing that this method will change the way people grow food.And，most importantly，it will help solve some of the issues related to hunger around the world.
（1）What does the figure in paragraph 1 show？ A．The necessity of growing food in the air. B．The number of hungry people. C．The seriousness of hunger. D．The existing population problem. （2）Why do people still starve to death in the world according to the text？ A．Food is not equally shared. B．Their basic needs are not met. C．There is not enough food supply. D．They have no scientific planting methods. （3）What is paragraph 4 mainly about？ A．The theory of aeroponics. B．The advantages of aeroponics. C．How to grow food in the air. D．The downsides of traditional farming. （4）What do viewers think of Ogbole's farming method？ A．Unrealistic. B．Funny. C．Promising. D．Helpless.

There are plenty of concerns about robots stealing jobs from hard-working，flesh-and-blood humans.However，Japan's Henna "Strange" Hotel has fired half of its 243 robot staff，because these labor-saving machines were causing more problems than they were solving— and requiring humans to come in and fix things as a result. One of the victims of the robot layoffs was a doll-shaped robot called Cheri，which functioned as an artificial intelligence assistant.Unfortunately.Cheri tuned out to be pretty poor at answering questions from hotel guests.A pair of dinosaur robots，which worked at the hotel check-in，were also made non-existent by the firings since they wound up being unable to do many of the jobs required of 8 receptionist.A concierge （服务台职员） robot，meanwhile，was replaced by a human better able to answer important questions about nearby tourist attractions.Humans are also now going to carry luggage to the rooms，one quarter of which the previous porter robots were only able to reach—and only in excellent weather conditions. Not surprisingly，the hotel，recognized in 2016 as the world's first robot-staffed hotel by Guinness World Records， allured curious visitors from all around the world.Encouraged by the success the hotel s owner，Sawada opened seven additional locations across Japan and announced plans to build at least 50 more. In the end，though，it seems that—as great as robots can be—they're simply not suitable for every role just yet.With the rise of robot bar-tenders，robot-staffed restaurants and the like，it will be interesting to see how many similar concepts fall apart in the coming years.After all，once the novelty of a dinosaur robot on reception wears off，you're just faced with a receptionist who can't properly understand you and lacks an effective number of fingers on each hand to properly photocopy your passport.
（1）Which of the following was used to answer such questions as scenic spots？ A．A porter robot. B．A dinosaur robot. C．A concierge robot. D．A doll-shaped robot. （2）What does the underlined word "allured" refer to in Paragraph 3？ A．attracted B．relaxed C．thrilled D．upset （3）What does the author think of the robot staff？ A．They did better than humans. B．They couldn't replace humans entirely. C．The rest of them will be fired. D．They were a big challenge for humans. （4）What might be the most suitable title of the text？ A．World's First Robot-staffed Hotel. B．Robots Perform Various Functions. C．Humans Will Replace Robots Eventually. D．Japanese Hotel Fires Half Its Robot Staff.

There's a new AI bot：ChatGPT，and you'd better pay attention，even if you aren't into artificial intelligence.The tool is an AI chatbot system that OpenAI released in November 2022 to show off and test what a very large，powerful AI system can achieve. ChatGPT remembers the thread of your dialogue，using previous questions and answers to inform its next responses.It derives（获得） its answers from huge volumes of information on the Internet.ChatGPT is built on top of the OpenAI GPT-3 family of large language models and is fine-tuned （a method of transfer learning） using both supervised and reinforcement learning （监督和强化学习）. You can ask ChatGPT anything，like explaining physics，asking for birthday party ideas and getting programming help.Perhaps it's not smart enough to replace all humans yet，but it can be creative，and its answers can sound downright authoritative（权威的）.A few days after its launch，more than 1 million people were trying out ChatGPT.UBS analyst Loyd Walmsley estimated in February 2023 that ChatGPT reached 100 million monthly users in January，accomplishing in 2 months what took TikTok about 9 months and Instagram two and a half years. ChatGPT is free to use at the moment because it is still in its research period.But when too many people hop onto the server（跳转到服务器），it overloads and cannot process your request.It just means you should try visiting the site at a later time when fewer people are trying to access it.If you want to skip the wait and have reliable access，there is a choice for you，ChatGPT Plus，which allows users to have general access even during peak times.This service does come at a cost of ﹩20 per month. However，ChatGPT cannot replace Google.ChatGPT is an artificial intelligence robot that provides solutions to your questions，but Google is a search engine in which you can search for as much information as possible.ChatGPT has limited knowledge due to its programming but Google has unlimited knowledge which is updated every day.
（1）What does paragraph 2 mainly tell us about ChatGPT？ A．Its working theory. B．Its language model. C．Its design inspiration. D．Its development process. （2）Why does the author list figures in paragraph 3？ A．To show the popularity of ChatGPT. B．To stress the high cost of inventing ChatGPT. C．To present the creativity of artificial intelligence. D．To prove the necessity of developing tools for chatting online. （3）What is ChatGPT Plus intended for？ A．Guiding users to experience free services. B．Giving users priority access during peak hours. C．Allowing net surfers to skip advertisements. D．Helping researchers detect the failure of the system. （4）What is a limitation of ChatGPT compared with Google？ A．It may provide replies unrelated to the questions. B．It can only update information at a fixed time C．It needs longer to provide solutions. D．It operates based on limited data.

There's a continuing controversy over whether electric vehicleould produce sounds to let the blind and other pedestrians know they're on the scene.Some think those soundould be standardized—like the"beep，beep"of heavy machinery backing up，so you'll think "something heavy is coming this way"when you hear it—— and some think any sound will do. This is a serious subject.Plug-in hybrid cars（电混动力车） and battery electric vehicles are super-quiet，and a study at the University of California，Riverside concludes that people listening to recordings on headphones can hear a regular gas car coming from 28 feet away，but a hybrid in battery mode only when it's 7 feet away. In response，the European Union has put new rules into play：all new electric vehicle models must have a sound-producing device，which sounds like a traditional engine.Starting in 2021，all new electric vehicles of any model will need the Acoustic Vehicle Alerting System or AVAS.That sound will come into play when the car is traveling backwards or when it's traveling at less than 12 miles an hour—speeds at which cars are more likely to be mixing with pedestrians. That's a nice start，say representatives for the blind，but more is needed."We're calling on the government to take this announcement further by requiring AVAS on all existing electric and hybrid vehicles and ensuring drivers have them switched on，" John Welsman，a guide dog owner and Guide Dogs staff member，said in a statement. Drivers in most cases have the ability to shut off the device when needed.My guess is that they will eventually be standardized so your mind will automatically register"electric car" when you hear it.And that's probably a good thing to reduce the mayhem（混乱） on the roads.
（1）How does the author show"electric cars are quiet"in Paragraph 2？ A．By making a classification. B．By making a comparison.； C．By analyzing cause and effect. D．By setting down general rules. （2）What can be learned about the AVAS？ A．It was developed by the European Union. B．It was designed for inexperienced drivers. C．It consists of a sound-producing device and an engine. D．It warns pedestrians of the coming of an electric car. （3）What does John Welsman think of the new rules？ A．They are too strict for drivers. B．They are too complex to follow. C．They need further improvement. D．They hardly allow for any flexibility. （4）Which of the following can be the best title of the passage？ A．Electric cars with a standardized sound-producing device. B．The increasing popularity of a new type of electric car on sale. C．The current problems with electric vehicles. D．Quiet electric cars' disorganization on roads.

Alibaba Cloud and the Hangzhou city government announced the launch of ET City Brain 2.0，a cloud-powered and AI-driven urban traffic-management system that aims to increase the city's efficiency. After over two years of testing in Alibaba's home base，ET City Brain has become the new infrastructure （基础设施） for Hangzhou，with a total coverage of 420 square kilometers in area，including over 1，300 traffic lights.Over 200 traffic officers are connected via mobile phones，enabling them to receive real-time alerts on any traffic-related emergencies. In version 2.0，the system will optimize the city's firefighting abilities by providing key information to firefighters，such as water pressure，the number and position of fire hydrants （消防栓） in a given area，the location of gas pipes and other details they need to know.The information is instant，making the entire firefighting process faster，safer and more accurate. City Brain gives meaning to data.By using AI and advanced algorithms （计算程序），City Brain is able to analyze a large amount of data and turn them into useful information in real-time speed. As a result of City Brain's ability to predict traffic flow，detect accidents and provide instant feedback，Hangzhou has dropped from 5th to the 57th on the list of China's most congested cities.Hangzhou is probably the only city that can tell you how many cars are on the street at any given time. In the case of medical emergencies，City Brain is able to change traffic lights，so emergency vehicles like ambulances and fire trucks can head to the scene without interruption，accelerating their arrival time by 49%. Dr.Wang Jian，head of Alibaba's Technology Steering Committee who invented the term "City Brain"，said the system is designed to empower a city to act quickly and directly.It is more than just about traffic management.It's really about how to make city more livable at a time of shrinking natural resources around the globe. "It is a matter of sustainability，while using as little natural resources as possible，" Wang said， "This is just the beginning."

The UK's largest and most advanced robotics centre，the National Robotarium，opened on Sep.28th，2022 in Edinburgh，is aimed to be a world-leading centre for robotics and artificial intelligence.It's hosted by Heriot-Watt University and the University of Edinburgh and received ￡21 million in funding from the UK government as well as ￡1.4 million from the Scottish government. Stewart Miller，the chief executive of the National Robotarium has said that society needs to prepare for the increased integration of robots but shouldn't fear the rise of artificial intelligence （AI）.He told Sky-News that "Necessarily there will be more robots in everybody's life.They'll be helping you at home，when you go out shopping，when you go to a hotel，they'll serve you，when you go to a theatre，everything.And in your working life." Internationally，some scientists have expressed concerns over rapid progress in the field of artificial intelligence.A new survey of researchers from the New York University Centre for Data Science found that more than a third （36%） of respondents that had published recent papers in the field thought that AI could produce catastrophic outcomes in this century， "on the level of all-out nuclear war". Mr.Miller said， "The thing to remember is that we，the humans，are in control.We decide how far it goes and doesn't go".He added， "A lot of people have already been working on making sure the software sitting behind AI has safeguards built into it." To make sure that，particularly when it's running on a robotic platform，it can't do any harm or at least we make sure it does as minimal harm as we possibly can.So those kinds of safeguards will be built in by the engineers. "We will have to put safeguards in place and make sure we have good controls around it，because artificial intelligence is a very powerful technology.But I think it has more things to bring that will be good than we have to worry about."
（1）What can we learn about AI from paragraph 2？ A．It brings fear to the whole society. B．It takes place of human labour. C．It helps human in many ways. D．It's generally applied to service industry. （2）What does the underlined word "catastrophic" mean in paragraph 3？ A．Disastrous. B．Dramatic. C．Surprising. D．Promising. （3）What measures have been taken to avoid the threat from AI？ A．Hiring safeguards. B．Setting up a security website. C．Purchasing security systems. D．Putting security software in place. （4）What's the text mainly about？ A．Security defense of artificial intelligence. B．No need to worry about artificial intelligence. C．Wide application of artificial intelligence. D．Major problems brought by artificial intelligence.

Facial recognition cameras are everywhere，including in your smartphone.Many people rely on this technology to unlock their phones，open doors or make quick payments，but everyone is wearing mask.What a hassle! Now，tech companies have updated their software.Facial recognition technology can now identify people even if they are wearing a mask. Beijing based tech company Hanwang has announced a software which can correctly recognize 95 percent of people wearing masks，Engineering &.Technology（E &.T） reported. What's the secret？It's all about your eyes. Marios Savvides，a professor at Carnegie Mellon University，US，studies facial recognition technology. "As we get older，" he said， "our faces change shape，but not the area around our eyes，It stays the same even if we put on weight." Another company has also been working on this kind of software.Tech5 has AI that measures the shape of your face.It also scans your iris （the colored part of your eyes）.Tech5 hopes to ignore all of the face below the nose. Facial recognition software is about more than just unlocking your phone.It's about public safety.Touehless verification （验证） has become extremely important due to the COVID 19，More than that，facial recognition can be used to fight crime （犯罪）."It can detect crime suspects，" said Hung Lei，Hanwang's CEO.Hanwang's technology is used by police in high-security settings. 'This means places like government buildings，subway stations and airports，Hung admits one big weakness of this new technology：It fails when people wear both masks and sunglasses. "In this situation，all of the key facial information is lost，but I believe we can overcome the weakness in the future，" said Huang.

What if your smartphone or laptop starts charging as soon as you walk in the door？Scientists have developed a specially-built room that can conduct energy to a variety of electronic devices within it without plugs or batteries. It's a custom test room of about 18 m3，built from conductive aluminum panels （铝板） with a metal pole running down the middle.When the scientists ran an electric current through the walls and pole following a set pattern，it produced two separate magnetic （磁的） fields：one that fills the center of the room and the other that covers the corners，thus allowing any devices within the space to charge. By carrying out tests，scientists found their method could deliver 50 watts of power throughout the room，firing up all devices they tested.Without safeguards，running currents through the room's metal walls would typically fill it with two types of waves：electric and magnetic.This presents a problem，because electric fields can produce heat in biological tissues and pose a danger to humans.So the team built capacitors，devices that store electric energy，in the walls. "It limits the safe magnetic fields to the room volume （室容积） while limiting risky parts to all the components built in the walls." lead author Takuya Sasatani explains. The scientists also tested the room's safety，and the result showed the absorption of energy would remain well below acceptable limits. "We're not saying this technology is safe under all circumstances — we're still exploring，" says study co-author Alanson Sample. "But it shows us that there's still much area to explore." But applying the technology is still far in the future. "It's just too troublesome to put aluminum sheets all over the wall — that benefit doesn't make sense yet，" Sample says. "We've just developed a brand-new technique.Now we have to figure out how to make it practical."

Can a small group of drones（无人机）guarantee the safety and reliability of railways and，at the same time，help railway operators save billions of euros each year？That is the very likely future of applying today's "eyes in the sky" technology to making sure that the millions of kilometres of rail tracks and infrastructure（基础设施）worldwide are safe for trains on a 24/7 basis. Drones are already being used to examine high-tension electrical lines.They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points.The more regularly they can be inspected，the more railway safety，reliability and on-time performance will be improved.Costs would be cut and operations would be more efficient（高效）across the board. That includes huge savings in maintenance costs and better protection of railway personnel safety.It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance，including sending maintenance staff，often at night，to inspect and repair the rail infrastructure.That can be dangerous work that could be avoided with drones assisting the crews' efforts. By using the latest technologies，drones could also start providing higher-value services for railways，detecting faults in the rail or switches，before they can cause any safety problems.To perform these tasks，drones for rail don't need to be flying overhead.Engineers are now working on a new concept：the rail drones of the future.They will be moving on the track ahead of the train，and programmed to run autonomously.Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot.With their ability to see ahead，they could signal any problem，so that fast-moving trains would be able to react in time.
（1）What makes the application of drones to rail lines possible？ A．Drones' ability to work at high altitudes. B．The use of drones in checking on power lines. C．The reduction of cost in designing drones. D．Drones' reliable performance in remote areas. （2）What does "maintenance" underlined in paragraph 3 refer to？ A．Inspection and repair. B．Personnel safety. C．Assistance from drones. D．Construction of infrastructure. （3）What function is expected of the rail drones？ A．To provide early warning. B．To earn profits for the crews. C．To make trains run automatically. D．To accelerate transportation. （4）Which is the most suitable title for the text？ A．What Faults Can Be Detected with Drones B．How Production of Drones Can Be Expanded C．What Difficulty Drone Development Will Face D．How Drones Will Change the Future of Railways

Virtual reality is quickly becoming the new technological frontier.Tech companies everywhere seem to be racing to get their foot in the VR door.However，Virtual reality has a set of challenges and hurdles that it must overcome in order to work well.It should be noted that VR is heavily dependent on being very fast，very accurate and very good-looking.If it isn't，the viewer will feel motion sick or disconnected from the world that VR is trying to create. Now that we can actually build VR headsets that begin to meet these requirements，we are seeing a rising interest in VR.As it rises，so does the interest in creating new media to be experienced in using virtual reality.Journalism is a medium built on relevance.Journalistould always be finding new ways to tell stories and deliver content.It is a goldmine for storytelling.What better ways to tell a story to someone than to put them right in the center of it？ Virtual reality is a powerful tool for journalists.The consumer isn't just reading or watching something play out；they're experiencing it.The immersive nature of VR allows for people to connect with the subject matter on a much deeper level than just reading about it.The experience is emotional，speaking more to our instinct than our intellect.The possibilities for storytelling here are legion，and any storyteller wanting to do something more interesting than their peerould surely be considering the sheer power of VR. The question of virtual reality，though，is not how powerful it is.That is immediately apparent.The question of VR is one of viability and availability.Telling stories must be easy to do，and access to those stories must be readily available.This is the biggest challenge that VR faces.If the tools to tell a story with VR，aren't easy to pick up and learn，VR will fail.If VR technology isn't both top-of-the-line and affordable，VR will fail. Accessibility was one concern for Thomas Hallaq，assistant professor of journalism and mass communications，who.said that current VR technology，is pretty exclusive right now.Despite that，he said he doesn't think the exclusivity of this technology will be a problem in the long run. "I think it's very promising，" Hallaq said. "We're seeing more technology become accessible，and more people having access to that technology.Just look at smartphones." Like radio，TV and the Internet before it，virtual reality will change the way we tell stories.
（1）Why is VR considered a powerful tool for journalism？ A．Because it is an exclusively new tool. B．Because it is very powerful and popular. C．Because people can experience the story in person. D．Because it is very fast，accurate and good-looking. （2）According to the passage，what is the biggest challenge VR is facing？ A．How powerful and interesting it can be. B．Whether people will have easy access to it. C．Whether qualified VR headsets can be built. D．What new ways people will find to deliver content. （3）What's the author's attitude towards the future of VR technology？ A．Optimistic. B．Neutral. C．Pessimistic. D．Concerned. （4）Which of the following is the best title for the passage？ A．The Wide Popularity of Virtual Reality. B．The Future Development of Virtual Reality. C．Challenges and Hurdles of Virtual Reality. D．Virtual Reality is the Future of Storytelling.

ChatGPT developer OpenAI has introduced a new tool that it says can reproduce human voices with just a short audio sample.The tool is among several tools developed by technology companies that aim to clone voices with a high level of exactness. The system is called Voice Engine.OpenAI released details about Voice Engine on March 29.The company also released some examples of how the tool performs.The company explained in a statement that the system uses written instructions and a 15-second audio sample to produce，or generate natural-sounding speech in the voice of any speaker. OpenAI said it has been working on developing the tool since late 2022.It plans to continue developing it before releasing it to the public.The company said the delayed release represents a cautious and wise effort to prevent possible misuse. OpenAI said it began testing Voice Engine with a small group of trusted partners.This testing aims to help company officials decide how to improve the tool's safety and learn how it can "be used for good" across different industries. There have already been highly publicized examples of false，or fake voice recordings that sound like well-known people. OpenAI said it is currently discussing how to limit these and other risks of such voice cloning systems.Technology experts have also warned such tools can be used to carry out financial crimes.For example，voices can be recorded and then reproduced to represent another individual in an effort to carry out a fraud. However，OpenAI listed several possible uses for the technology tool.These include providing reading assistance to non-readers or children，supporting individuals who cannot speak，and helping patients recover their voice. The company said its Voice Engine system can work in several languages.One example of such use is taking an English voice recording and producing a new audio version in another language.In an example released online，OpenAI proved a person's voice and style of speaking can remain the same in other targeted languages.
（1）What's the main function of OpenAI's new tool？ A.To help the disabled. B.To clone human voices. C.To chat on the Internet. D.To make records of sounds. （2）Why has the release of Voice Engine been put off？ A.To ensure its safety. B.To overcome its errors. C.To ask for user feedback. D.To wait for official permission. （3）What does the underlined word "fraud" in paragraph 6 mean？ A.Task. B.Investigation. C.Cheat. D.Test. （4）What do we know about Voice Engine？ A.It can translate languages exactly. B.It can teach children how to read. C.It can make language study easier.
